Why am I running out of memory when I multiply a sparse matrix and a vector:
sage: A 71604 x 143208 sparse matrix over Real Field with 53 bits of precision (use the '.str()' method to see the entries) sage: A.density() 95465/3418088544 sage: x0 143208 x 1 dense matrix over Real Field with 53 bits of precision (use the '.str()' method to see the entries) sage: x1 = A * x0 (after a while... out of memory) -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
